How to diagnose a Jeep JK radiator fan issue?
The Relay in the TIPM (K11) labeled “Radiator Fan Low” The dual relays over by the brake master cylinder labeled “Fan Relays” on the internet (Mopar Part 56055666AB) The lack of a P069X style code being thrown led me to believe this was a unique problem with only the “high” speed part of running the fan.
How much does a JK radiator fan cost?
The fan expects to get power from the battery at all times (so it can run even when the car is off), and translates the PWM duty cycle signal from the computer in the TIPM into a variable speed for the fan itself. Consequently, the fan for a 2011 and prior JK Jeep is around $65 to $200 dollars, and there is a ton of aftermarket competition.
Why do newer Jeeps have less fan failures?
The newer Jeeps are… newer, and as a result parts are failing a lot less often. I suspect that as they age and parts fail more, this knowledge will become a lot more common.
What does code p0480 mean on Jeep radiator fan?
Include a few extra bits of circuitry (more relays) that help trigger the fan on when the AC is running, or the engine temp crosses a certain level. In addition to throwing a P0480, these fans can also throw a code in the P069X range.

Why does my car have a radiator fan?
You probably already know the purpose of the radiator and the cooling system in your car. When you are driving fast, the wind is passing through the radiator to cool the coolant down without issues, but when you are driving slow, there is no wind pushed through the radiator. This is why we use a radiator fan.
What was the problem with my Jeep Wrangler JK Unlimited?
Recently, I was driving my 2015 Jeep Wrangler JK Unlimited through a parking lot on a 95 degree day, and after leaving a stop sign, a check engine light flashed on (later I would learn it was a P0480 Cooling Fan Relay 1 Control Circuit ), and shortly thereafter my Jeep overheated.
